Void Type

void is a special type indicating the absence of any value. There are no objects of void; instead, void is used for deriving more complex types.

Void Functions

Use the void keyword as a function return type if the function does not return a value. For example:

void print_temp(char temp) { Lcd_Out_Cp("Temperature:"); Lcd_Out_Cp(temp);

Lcd_Chr_Cp(223); // degree character

Lcd_Chr_Cp('C');

}

Use void as a function heading if the function does not take any parameters. Alternatively, you can just write empty parentheses:

main(void) { // same as main()

...

}

Generic Pointers

Pointers can be declared as void, meaning that they can point to any type. These pointers are sometimes called generic.
